I have a X10SLM-F firmware 1.24. Active directory authentication does not work with my primary domain. When I put in my full domain name in the configuration, it says that it saved the changes, but the settings are not saved. If I enter a shorter domain, it saves the settings. Here's a summary of the problems I found:
1. Domain names of length 16 characters or more (including the .) are not accepted.
2. Passwords of length 20 or more characters do not work (19 characters works).
3. Passwords with special characters do not work.
Long usernames don't seem to be a problem.
2. Set the password for ipmitst to a 20 character password - it did NOT work.
3. Created users called extremelylong,superextremelylong, and aaaaaaaaaaaaaaaaaaa. All of them worked with short passwords.
4. Changed the password of superextremelylong to one with special characters, but under length 20. It did not work. Removing the special characters worked.
For the X10 motherboards, this has been solved on 1.38 FW. For the web interface special characters are restricted, and only 19 characters are allowed at the moment.
